Embodiment Construction

[0048] It should be noted that, in the case of no conflict, the embodiments of the present invention and the features in the embodiments can be combined with each other.

[0049] At present, in the prior art, it is impossible to accurately judge whether the filter screen needs to be cleaned, so that the filter screen of most air conditioners is severely blocked by dust, which affects the ventilation volume, thereby affecting the cooling and heating effects, and increasing power consumption. In view of this, the present invention provides a dust accumulation judging device, method and air conditioner to solve the aforementioned technical problems.

[0050] The present invention will be described in detail below with reference to the accompanying drawings and examples.

[0051] The embodiment of the present invention provides a dust accumulation judging device, please refer to figure 1 , the dust accumulation judging device includes: an acquisition module 1 for acquiring the op...

Abstract

The invention provides a dust accumulation judging device and method and an air conditioner. The dust accumulation judging device includes an acquisition module and a judging module, and the acquisition module is used for acquiring an operation state of the air conditioner, a detect temperature T<detect> of the surface of a heat exchanger, a temperature T<heat exchanger> of a heat exchanger coiledtube and an indoor temperature T<indoor>; and the judging module is used for judging whether a filter screen is in a blocked state or not according to the operation state of the air conditioner, theT<detect>, the T<heat exchanger> and the T<indoor>. According to the dust accumulation judging device and method and the air conditioner, whether the filter screen is dirty and is blocked or not can be effectively judged according to the operation state of the air conditioner, the T<detect>, the T<heat exchanger> and the T<indoor>, so that users are warned to clean the filter screen in time, the effects of cooling and heating are improved, and the purpose of energy consumption lowering is achieved.

Description

technical field [0001] The invention relates to the technical field of air conditioners, in particular to a dust accumulation judging device and method and an air conditioner. Background technique [0002] When the air conditioner is running, it needs to exchange heat between the indoor air and the heat exchanger of the air conditioner, so as to obtain cooling or heating effects. However, there is inevitably dust in the indoor air. If the dust sticks to the heat exchanger, it will affect the heat exchange effect. Therefore, the air conditioner will be designed with a filter to intercept the dust on the filter to ensure the cleanliness of the heat exchanger surface. [0003] As the running time increases, the dust on the filter will accumulate more and more, which will eventually affect the ventilation rate of the air conditioner and also affect the heat exchange effect. Therefore, the filter needs to be removed and cleaned regularly. In the prior art, since there is no dust...
